Finn Comfort Classic Footbeds 9540; Size 38 EU, 7.5-8 US. Excellent NEW condition.
The 9540 original (firm) removable footbed fits these Finn Comfort shoe models: Amalfi, Baltrum, Harper, Hollister, Korfu, Sylt, Venice. See "Models at a Glance" at https://www.shopfinncomfort.com/media/models-at-a-glance.pdf.
I removed these footbeds from brand new shoes and replaced them with the soft version, since I have very sensitive feet.
Instead of custom orthotics, I use removable footbeds in my slippers, sneakers, and hiking shoes when space allows.
